The Stealth 50 is a simple power meter that is ANT+™ compatible, so it works with CatEye or third party ANT+™ power, heart rate, cadence and speed sensors. Track basic cycling data and combine with power, heart rate and cadence data to target and reach training goals. Upload ride data to web-based training sites, such as CatEyeAtlas.com and TrainingPeaks™, where you can visualize your activity, analyze performance and share your ride.
Other features include a full-time backlight, auto-stop/start and programmable odometer. The Stealth 50 is waterproof, USB rechargeable and can be used on multiple bikes, so you’ll always be ready to ride.

Make and model: Cateye Stealth 50
Tell us what the product is for, and who it's aimed at. What do the manufacturers say about it? How does that compare to your own feelings about it?
For the average buyer it will be seen as a direct competitor to Garmin's lower priced units, it's very easy to swap between bikes and web uploads/downloads are easy once you've digested the instructions. The screen isn't as programmable as a Garmin but the single mode button to scroll between information is quick and easy. Theoretically compatible with PCs and Intel Macs but we couldn't get it to talk to an older Intel Macbook

Rate the product for quality of construction:
Rate the product for performance:
No issues at all apart from the frustration that we couldn't get it to communicate with an early Intel Macbook.
Rate the product for durability:
Long term durability unknown so far.
Rate the product for weight, if applicable:
Rate the product for value:
Good value as it is. Best value package is if you buy the heart monitor and speed/cadence sensor at the same time.
Tell us how the product performed overall when used for its designed purpose
Easy to use. Most riders will be happy with the info provided and the uploads to maps on www.cateyeatlas.com is useful.
Tell us what you particularly liked about the product
Simple to use once the instructions are digested. Good screen display in normal light and easy to scroll between screen info. Backlight is useful. Easy to use on a home trainer without a GPS signal (if you buy the speed/cadence sensor upgrade).
Tell us what you particularly disliked about the product
Wouldn't work with an early Intel Macbook. Screen hard to see in certain angles of sunlight.
Did you enjoy using the product? Yes.
Would you consider buying the product? Yes.
Would you recommend the product to a friend? Yes.
Anything further to say about the product in conclusion?
We'd be happier if communication issues with early Intel Macbooks could be resolved, but otherwise does exactly what it says on the tin.
